MAF1005GAD571DT000

Chip Ferrite Bead Overview

The TDK MAF1005GAD571DT000 is a surface-mount ferrite bead from the MAF-G series, designed for noise suppression in cellular band applications. It features a 0402 (1005 metric) package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height. The component exhibits an impedance of 80 Ohms at 100 MHz and a maximum DC resistance of 270 mOhms. It supports a maximum DC current of 900 mA and operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides effective noise suppression specifically targeted at cellular frequency bands.
• Utilizes a compact 0402 surface-mount footprint for space-constrained circuit designs.
• Maintains stable electrical performance across a wide industrial temperature range.

Chip Ferrite Bead Applications

• Cellular communication module signal line filtering
• High-speed digital interface noise attenuation
• Portable electronic device power rail stabilization

Chip Ferrite Bead Procurement Notes

Verify the specific impedance value against the official datasheet, as distributor listings may show conflicting specifications such as 570 Ohms or 80 Ohms. Confirm the package dimensions and RoHS compliance status directly with TDK documentation before integration. Ensure the selected variant matches the required current rating and DC resistance for the target application circuit.

Chip Ferrite Bead Selection Notes

Select this component when a low-profile 0402 ferrite bead is required for cellular band noise suppression. Evaluate the 900 mA current rating against the peak load requirements of the circuit. Consider the 270 mOhm DC resistance impact on voltage drop. Compare alternative impedances if the primary noise frequency differs significantly from the 100 MHz test point.

Chip Ferrite Bead Part Context

This part belongs to the TDK MAF series of chip ferrite beads, which are engineered for electromagnetic interference suppression in compact electronic devices. The MAF-G sub-series specifically addresses high-frequency noise in mobile and wireless communication systems. These components are widely used in smartphones, tablets, and IoT modules where size constraints limit filter options.
